I believe I've considerably cleaned it up. However, I don't usually edit Wikipedia pages and it could probably be brought up to speed Wikipedia-wise Weston.pace 22:47, 24 May 2007 (UTC)[reply]

I agree. I hope the original author decides to edit -- This reads like notes taken during a lecture. Fonny 13:18, 17 April 2007 (UTC)[reply]

C4.5 is considered to be pretty important in the machine learning community (at least, I see it a lot in papers about text classification -- usually being beaten by support vector machines on particular datasets) so this page is noteworthy. However, it has terrible English. I'm not familiar enough with the software/algorithm(s) involved to edit it seriously. Whenning 05:23, 3 February 2007 (UTC)[reply]

Discussion of improvements

This article and the restatement of ID3_algorithm should be replaced with an explanation of the improvements offered by C4.5. From the article:

Choosing an appropriate attribute selection measure.
Handling training data with missing attribute values.
Handling attributes with differing costs.
Handling continuous attributes.

What does C4.5 do in each of these areas? Details about the implementation are useless! --Beefyt 21:55, 24 April 2007 (UTC)[reply]

J48 algorithm

J48 redirects to this page, though this article doesn't mention it.. are there significant differences between C4.5 and J48 or is J48 no more than a Java implementation of C4.5? Thanks, Simeon87 (talk) 12:16, 28 May 2008 (UTC)[reply]

Pseudocode doesn't discribe the C4.5 algorithm

The listed pseudocode is only a basic decision tree induction algorithm but not the C4.5 algorithm (if you check the source you'll see that kotsiantis didn't describe the C4.5 algorithm in any listing). I'm not sure if it was planned to just list a general decision tree induction algorithm, if so it would be helpful to note this. --B.eberhardinger (talk) 09:42, 24 June 2011 (UTC) Benedikt Eberhardinger[reply]
